    I have a 88 GT 308N/A.with Motorsport 1.72 stud mount rockers.Every 3 runs they start tapping like crazy.4 times i adjusted them and 3 runs is all they last.Im thinking its got 2 be a bad lifter.Just ordered new lifters and pushrods.Anyone else have this problem or know the solution.Also i marked the rockers last time i adjusted them and everything is in the same spot but they tap like hell???

    this is what you should do.

    on TDC compresion for each cylinder - finger tighten the rocker arms til there is no play up and down on the pushrod. crank them 1/2 turn and lock them down.

    Just out of curiosity, what did LaRocca's say they thought the problem was? They are purported to have some experts there.

    At Laroccas it was the first time they came loose so it was not know that there was a problem at that time.I tried calling and can never get a tech on the phone to give me there opinion.They took my # down and im still waiting for a phone call??????
